PR rtl-optimization/48141
* params.def (PARAM_MAX_DSE_ACTIVE_LOCAL_STORES): New.
* dse.c: Include params.h.
(active_local_stores_len): New variable.
(add_wild_read, dse_step1): Clear it when setting active_local_stores
to NULL.
(record_store, check_mem_read_rtx): Decrease it when removing
from the chain.
(scan_insn): Likewise. Increase it when adding to chain, if it
reaches PARAM_MAX_DSE_ACTIVE_LOCAL_STORES limit, set to 1 and
set active_local_stores to NULL before the addition.
* Makefile.in (dse.o): Depend on $(PARAMS_H).
